Sam, 23 Dec 2013Thanx in advance......but if again restart problem occur then wht to do???you will have to Downgrade your phone & upgrade.
use 3rd party softwares for Downgrade your iOS. then upgrade to iOS7.0.4 via iTunes.
It is a software issue. Not a Hardware issue.

upgrading iPhone4s to next OS versions creating so many problems. one of the example is "WiFi grayed out".
my personal experience. I have upgraded iphone4s to ios7 version with a week or so. WiFi got grayed out, after serching so many blogs got to know that it's a hardware issue and it never comes back to normal state.
finally been to apple stores(Aptronix) they replaced my device with new one, since I was in warranty i got the new device. else I had to use iPhone without WiFi and Bluetooth forever or buy new one. Or may be they will charge me for their mistake.

This is very disappointing thing from the big brand Apple.

I hope they won't repeat this kind of unsolvable issues in there coming new set of devices.

Wealthy man, 19 Dec 2013Still more beautiful than iphone 5 especially the black modelHi guys I have 4s' before I used my phone very smooth but now I could not connect any wifi and when I restart my phone my wifi is greyout not posible to open now I try all suggestion that read but all not working please help my phone is out of warranty

Battery back up is great for me on 7.0.4. All settings are on default except Facetime and imessage which I dont use. I have unlimited data plan and cellular data is on 24h/day. Email accounts are synced in real time, skype always on, I talk 30min/day average and surfing the web around 2h. With this usage I'm getting full day battery backup with 30% remain around 10PM. If I play games or setup wifi hotspot my battery drain in 4h.

I heard lot of complaints about 4s battery but mine is performing great. Friends with same phone and similar usage get a way less battery backup than me. The only conclusion is that battery backup is not the same for all device.

CoolAnksss, 16 Dec 2013Hii guys.. Plz suggest me...iPhone 4s with 8gb internal memory is enough or not..It depends on your usage. U only got 5gb available space. Its very limited. Just install the most used apps and some lite games. U need to spare some space for media also. Most of social apps will store a ton of data. So,think wisely.
